Voice over IP Security focuses on the analysis of current and future threats, the evaluation of security products, the methodology of protection, and best practices for architecture design and service deployment. The book concentrates on very practical information, covering technology concepts and issues but also providing detailed design solutions, current products, and protocols, so that you can deploy secure VoIP service in the real world with confidence.
Coverage in the book includes an in-depth review of VoIP security fundamentals, samples of VoIP security best practices, as well as a section on lawful interception (CALEA). This final area provides, from a service provider perspective, every aspect of Lawful Interception from understanding of policy (government requirement, ISP responsibility) to designing of full service architecture.
